Well it could switch to point filtering when you zoom in, but if your object is scaled smaller than 100% size, it will still show more detail when you're zoomed in - the same way the runtime's zoom works. So I guess it should be left like that to reflect the runtime? Unless you deliberately want to make pixel perfect adjustments...

[quote="work3":2vt6zwtr]would there any way to turn off the filtering when it scales?[/quote:2vt6zwtr]
Yep, in Layout properties choose "Application - Properties". Then at "Runtime Prop." there is "Sampling - Linear" change it to "Sampling - Point" and viola u have pixels.
